This is good news - CoreOS needs to focus on what's most important to their core business to be successful.
Being chock full of bright, relatively young and enthusiastic engineers drunk on the Golang kool-aid, there's a very real risk of getting distracted by reimplementing everything under the sun in their favorite shiny new language.
Even if Torus is a good idea, CoreOS has to prioritize, commit, and execute. They can't afford too many diversions. This is a competitive space, their opportunity window and runway are both limited, as usual.
The human body is a complex system, with hormones controlling how energy is stored and made available, and nutritional content continuously altering the levels of those hormones.
Your statements completely ignore variables such as:
Bioavailability of the calories - how much of it remains in the waste (urine/feces) or is being metabolized by gutteral bacteria, for example. These variables strongly depend on the types of calories consumed, particularly the presence of dietary fiber. Soluble fiber for example is especially effective at capturing sugars and preventing their absorption in the small intestine, resulting in flatulence after arrival in the large intestine.
Insulin levels - when insulin levels are high energy is stored as fat. Hormones like insulin also influence mood and activity levels. Obese people are generally lethargic and low-energy/low-activity individuals, regardless of what is obviously an excess of energy available. This is due to the hormonal dysfunction. Hormones can cause a person to be internally starving when they're ingesting excessive calories, simply because their hormones are signaling the fat stores to effectively steal all the energy in the blood stream.
